7�4 Adjust end positions for version with signaling gear
PROFITRON actuators are either available with signaling gear or as "non-intrusive“ version with
the non-intrusive position encoder. End position adjustment for HiMod and PROFITRON with the
non-intrusive position encoder is described in chapter 7.5.
7�4�1 General information
If actuators are delivered mounted to a valve, this step has usually been done in the valve manu-
facturer’s factory. The setting has to be checked during commissioning.
For 2SG7 and 2SQ7 part-turn actuators, the signaling gear ratio does not have to be set. These
actuators are not equipped with an adjustable signaling gear. Continue with chapter 7.4.3
Position recording functional principle
By setting the signaling gear ratio and the end positions, it is ensured that length as well as start
and end of the valve travel (end positions OPEN and CLOSED) are correctly signaled to the elec-
tronics unit.
